Weeks 9-13 are your 3rd month. Day one of week 14 is the first day of the second trimester

I took that from the site given above baby2see.com

What is the length of the first, second and third trimesters?
The length of the trimesters is often a source of confusion. The word trimester means 'three months'. Three periods of three months each, gives pregnancy a beginning, a middle and an end period.
These periods match the developmental stages to divide up a pregnancy.
•Beginning: From LMP to 12 weeks the embryo develops all the major organs, becomes a fetus, and the placenta takes over control.

•Middle: From 12 weeks to 27 weeks the fetus continues developing and reaches viability.

•End: From 27 weeks on the fetus finishes development and prepares for delivery.

I'm wondering the same thing because I heard 12 weeks but this pregnancy app says week 13 starts your 2nd trimester :/ I'm 12 weeks 3 days! Congrats mamaellis

I'm pretty positive its 13

[Jessiebaby21]

It starts at the end of 12 an the beginning of 13 weeks

[baby2_on_the_way]

no it starts at 12 weeks!

i usually go by the months not weeks it would be week 13 i guess because there is 4 weeks in a month and you got 4/8/12 so your 12 wks now so it should have started at 12 weekss or it will start at 13 weeks

13 I think if you go to baby2see.com it will give you a breakdown of the trimesters
